Serial No. 485,245.

To all 'whom tt may concem:

Be it known that I, ALEXANDER KnzYwmo, a citizen of the Russian Empire,and resident of *Warsaw in the Kingdom of Poland, Russia, have inventeda certain new and useful Improvement in Incandescent Lamps, of which thefollowing is a specification, such as will enable others skilled in theart to which it app'ertains to make and use the same.

This invention relates to an improved incandescent lamp for the burningof vapor obtained from liquid without the application of artificialpressure.

The invention is preferably used with a mantle or net of known orconvenient construction and the lamp can be advantageously made fromsteel or other metal and is practically fire proof.

The particular construction of the lamp as hereinafter described makesit especially suitable for domestic use although equally applicable foruse in other ways.

In the accompanying drawing a simple example of the invention is shownin which a lamp base has a container 1 for the combustible liquid whichis open to the air through the cap 2, by the orifice 2a. A feed pipe 3is carried downward from this container to the lower end of thevaporizer 4, the top of which vaporizer is furnished with a nipple 5arranged below a mixing chamber 6. The vapor passing from the chamber 4through the nipple 5 draws air with it into the mlxing chamber, themixed air and gas passing partly upward through the wire gauze 14 to themantle 15 and partly downward by pipe 7 to the annular chamber 8 coveredwith wire gauze or other metal net 9 arranged around the vaporizer landinside the chamber 11. The vapor passing through the gauze 9 is ignitedas shown at 10 and the fiame is used to automatically vaporize theliquid in the vaporizer 4;. The lamp may be lighted by means of a pieceof asbestos soaked in alcohol, for instance, attached to a wire, andinserted through the orifice 11a, under the burn'er. The burned gasesfrom the chamber 11 pass by means of pipe 12 into the chimney or eXhaust13 arranged around the mantle 15. The flow of the mixture is clearlyindicated by the arrows 16.

It will be seen that the lamp shown in the drawings is w-ickless andthat the vaporizer is arranged partly above and partly below the levelof the liquid which is fed to it by gravity, suflicient pressure beingobtained on the liquid in the Vaporizer automatically from the supply inthe receptacle 1. From this it will be seen that a perfect lamp and nota burner only is obtained and it will be obvious that a filtering orother device may be embodied in the invention for the purpose ofpurifying the Vapor or the liquid and wicks can be used if necessary.

The lamp is worked in the following nianner. The vaporizer 4 is firstheated in any desired way, for example by means of alcohol through theorifice 11a, as said above, and thus the vaporizing of the liquid in thechamber 4 is started and as long as the supply lasts it willautomatically maintain itself, the vapor passing as above describedthrough the nipple 5 into the chamber 6 and from there to both themantle 15 and the tube 7 To extinguish the lamp any suitable means suchas the valve 'Z'a of covering or stopping the passage 7 is sufiicient.

It must be understood that the lamp can vary in form from that shown andthe size and shape of the vaporizer altered to suit requirements and ifwished the nipple 5 can discharge the vapor downwardly or otherwiseinstead of in an upward direction as shown. The particular constructionof the lamp and the combination of the vaporizer which is partly abovethe level of the liquid and is heated on the Bunsen system enables amore compact and Stronger lamp to be made than has been hithertopossible with the devices previously used and the dispensing` with theartificial pressure hitherto necessary simplifies the construction andit will be clearly seen that the extension of the 'vaporizer above thelevel of the liquid ent-irely prevents the flow of the liquid out' ofthe same.

What I claim and desire to secure by Letters Patent is i An incandescentlamp for burning combustible liquids comprising a container freely opento the air, a vaporizer communicating with said container and having oneof its ends located below the container, and the other above, a nippleon the vaporizer, a heating chamber surrounding the vaporizer, a mixingchamber opening above the nipple and having at its top an incandescentmantle, a chimney forming a Chamber about the mantle, a'ppe branchng InWtness whereof I have hereunto set from the mXng Chamber to the base ofthe my hand in presence of two Wtnesses.
